Plugin Option: Trail

trail creates a trailing effect by retaining particle states for a number of frames.

Example

trail: {
  enable: true,
  length: 20,
  fill: { color: { value: "#ffffff" } },
}

Notes

• length controls trail persistence; higher values create longer trails.
• The fill option defines trail color and opacity.
